Sage 100 was first introduced as MAS 90 (Master Accounting Series for the 90’s) in the mid-1980s by a company called State of the Art, Inc. located in Irvine, CA.
The Sage Group PLC purchased State of The Art in 1998 and shortly thereafter renamed MAS 90 to Sage 100 (perpetual licensing) and now to Sage 100cloud (subscription licensing).
According to this 2018 external roadmap posted in February 2018 by Sage, there are 24,600+ customers of Sage 100 and Sage 100cloud.
